The second installment deals with an East Syriac philosophical manuscript known as Mosul 35 preserved at the collection of the Chaldean Patriarchate. Besides a somewhat imprecise description by A. Scher there is no proper study of the manuscript and its content. The first part of the codex includes works related with Aristotle’s Organon (including two short lives of Aristotle), while the second part contains the philosophical compendium Teḡraṯ teḡrāṯā by Gregory Bar ʿEḇrōyō. A preliminary examination demonstrates that the manuscript is one of the earliest East Syriac philosophical manuscripts produced in the early modern period. Moreover, it is highly likely that it served as a model for at least three manuscripts (Sachau 226, Sachau 211 and Vat. sir. 593/III).
